INDEX-HOLDING MEANS.

Specification of Letters Patent.

Patented Oct. 28, 1919.

To all whom it may concern:

Be it known that we, PHILIP MUELLER and ANTON C. SOHUERMANN, citizens of the United States, residing at Decatur, in the county of Macon and State of Illinois, have invented new and useful Improvements in Index-Holding Means, of which the fol lowing is a specification.

This invention relates toindexes for cocks, and other articles, and has particular reference to means for securing the indexes in place.

The principal object of this invention is to provide an index holding means the parts of which are separable so that the index may be easily removed from the cook or other article to which it is attached, and so that other indexes may be readily substituted to designate the cock or article as desired. Briefly stated, the invention comprises a cap nut for engagement with the cook or article, having an open. outer end re ceiving therein a ferrule into which is burnished or otherwise suitably secured an index, and a securing member connected to the ferrule and nut for detachably holding the ferrule in place.

Other objects and advantages of this invention will be pointed out in the fOllOWiIlg detail description of the present embodiment of the invention, and from the accompanying drawing wherein- Figure 1 is a side elevation, partly in section, of a self-closing cock having the improved index holding means applied thereto.

Fig. 2 is an enlarged detail section of the index holding means and adjacent parts of the cock.

Fig. 3 is a similar view of a modified form of index holding means.

Fig. 4 is a detail view in elevation showing the index and supporting ferrule of Fig. 3.

Fig. 5 is a view similar to Fig. 2 but showing a further modified form of index hold-- ing means.

Referring to this drawing wherein the improved index holding means is shown as applied to a self-closing cook, 10 designates the body of the cock which is open at the top, 11 the upper cam trackway thereof and 12 the detachable handle mounted on the upper trackway and adapted to turn the same for manipulating the cock 10. As shown in the drawing the handle 12 engages at its mner end over the track-way 11 and the track.-

way and the handle have eorrespondingserrated or toothed portions which interfit to hold the handle from turning on the trackway 11 as indicated at 13. The track-way 11 has a threaded sleeve portion 14 rising above the handle 12 and through which passes the stem 15, see Figs. .2, 3 and 5,. of the cock. This structure is disclosed in the present drawing simply for the purpose of illustrating one application of this invention and it will be understood that the holding ings, and particularly to the latter, the

threaded portion 14 is provided with an.

open cap nut 16 which is turned down upon the threaded portion 14 for engagement with the handle 12 to hold the same upon the track-way 11. This cap nut 16 is internally threaded at its inner end for engagement with the threaded portion 14, is provided with a short smooth inner surface intermedlate its ends and has a reduced outer end providing an internal shoulder 17. A ferrule 18 is provided upon its outer end with an index 19 bearing the desired indicia and which may be of any desired and adaptable form, the index 19 being burnished or otherwise suitably secured in the outer end of the ferrule 18. Theferrule 18 is adapted to fit snugly down into the cap nut 16 and within the threaded portion or trackway 14. The ferrule is provided midway of its ends with a peripheral flange 20 adapted to engage the I shoulder 17 of the cap .nut and a packing ring .21 is placed within the cap nut between the extremity of the threaded stem 14 and the flange 20. Since the inner end of the ferrule 18 passes down into the trackway 14 the packing 21 is closed in on all sides and is adapted to be compressed against the stem 14 by the cap nut 16 when the latter is screwed down against the handle 12 so as to hold the ferrule frictionally against accidental rotation, leaving it, however, free to be moved by hand for adjustment.

In assembling this index holding means the packing ring 21 is placed about the lower end of the ferrule 18 and the latter is fitted down into the stem 14. The cap nut 16 is now passed over the ferrule 18 and screwed down upon the stem 1 f bringing the shoulder 17 against the flange 20 and bindmg the parts together. Thus the index ma be readily applied to the stem lat, may be turned to the desired angle with respect to the stem 1 and may be quickly and readily removed.

In Figs. 3 and 4 of the drawing is shown a modification of the invention wherein the cap nut 16 has a counter-bore in its outer end providing an internal shoulder 17 The index 19 is provided with a ferrule 1S which has its lower end slotted or otherwise formed to provide spring tongues 21. In assembling this structure the cap nut 16 is screwed down upon the threaded stem 14 and the tongues 21 are compressed and forced down into the counter-bore of the cap nut and are adapted to seat upon the shoulder 17*. Thus, the tension of the spring tongues 2i holds the index 19 and its ferrule l8 yieldingly in the cap nut.

In the further modification shown in Fig. 5 of the drawing, the cap nut 16 is provided with the shoulder 17, as in the instance of the structure of Fig. 3, While the counterbore of the cap nut has. in its inner wall an annular groove or recess receiving the pack ing 21*. The index 19 is carried upon a ferrule l8 which fits tightly into the outer end of the cap nut 16 and is provided with a smooth exterior surface against which the packing 21 is adapted to bind to frictionally hold the ferrule 18 to the cap nut.

In assembling this latter structure the cap nut 16 is turned down upon the stem 14, the packing 21 fitted in the groove of the cap nut and the ferrule 18 pressed down into the cap nut against the packing 21 The advantage of the above disclosed structures is evident since if it is desired to change the designation of the article carrying the index all that is necessary is to operate the parts so that the securing or conneeting means, the packings 21 and 21* or the spring tongues 21 may be separated from one or the other of the members, such as the cap nut 16 and the ferrule 18, and the index mounted on the ferrule may be turned into any desired position upon the cap nut.

l/Vhat is claimed is 1. In a self closing cock, an open topped cock body, a valve stem projecting therethrough, a cam track-way surrounding said stem within said body and projecting through the open top thereof, an open topped cap nut positively engaging the projecting end of said cam track, and an index sleeve rotatably mounted in said cap nut and covering said projecting stem.

2. In a self closing cock, an open topped cock body, a valve stem projecting therethrough, a cam track-way surrounding said stem within said body and projecting through the open top thereof, an open topped cap nut positively engaging the projecting end of said cam track, an index sleeve rotatably mounted in said cap nut and covering said projecting stem, and means frictionally to hold said index sleeve against accidental rotation.

3. In a self closing cock, an open topped cock body, avalve stem projecting therethrough, a cam track-way surrounding said stem within said body and projecting through the open top thereof, an open topped cap nut positively engaging the projecting end of said cam track, an index sleeve rotatably mounted in said cap nut and covering said projecting stem, engaging means between said index sleeve and said cap nut positively to lock said sleeve against vertical movement, and packing between said index sleeve and cap nut frictionally to hold said sleeve against accidental rotation.

In testimony whereof we have hereunto set our hands in presence of two subscribing witnesses.
